I've got to wonder if it's as big an issue if patients don't remember the pain. It seems to be like the tree-falling-in-the-woods problem: if a patient feels pain but never remembers, as far as he's concerned, did it really happen?

I have very hazy memories of wisdom tooth extraction. No pain, but very hazy. It doesn't bother me.

when I was a kid, I used to bike to school. I had a type of thought experiment. Biking uphill was difficult for me. I would have liked to teleport to the top of the hill and be over with it. What I would do was before starting the hill, I would say to myself that I'm going to teleport. Then I would try hard not to think. Then when I got to the top of the hill, I would snap back to it and pretend that I teleported to the top of the hill.

I would always wonder if I could use the same logic for surgery

Especially in the case of an intubated patient with neuromuscular blockade, I don’t think an EKG would be useful. You’re already going to have all kinds of fluctuations from the anesthesia, muscle relaxants, analgesics and just from the intubation. I’ve read about the use of EEG [1] as a way to detect awareness, but it has serious limitations. Most of all though, many anesthetic agents have a profound effect on the a…

Paralytics used in surgery impact voluntary muscle control only, they have very little in the way of effect on things like heart rate. Heart rate is absolutely monitored closely during surgery (precisely because it can be an indication of inadequate sedation).

Paralytics primarily effect voluntary muscles (and spontaneous respiration), but GA impacts the autonomic system to varying degrees. The blockade will keep you from moving (or breathing), the GA will depress your autonomic functioning. Now it’s true that the anesthesiologist will monitor your heart, but they have to interpret the cause of any change. If they don’t realize that the change in heart rate is due to awareness, you’re screwed.

I've woken up during surgery (for appendix removal). It was uncomfortable but not especially painful. I didn't feel panicky or disoriented, but then I've always been OK with medical situations. The anaesthetist looked pretty horrified though.

My spinal analgesia for an unplanned c-section utterly failed. My anesthesiologist thankfully kept it together and immediately went to our discussed plan B, but I felt so bad about it that I sent her a gift basket. I wonder how common that all is.

Are you a redhead by any chance? Red hair is linked to anesthesia resistance, requiring about a 20% higher dose to get the same effect as other people.

I woke up during my wisdom teeth surgery. Actually, I'm not even sure I did, but I remember doing it. The doctors never told me anything about it. I remember waking up and seeing something covering my eye, and moving my hands to do thumb ups and peace signs (I knew there were students in the room watching the surgery), and then I remember hands trying to immobilize me, and me trying to start thumb wars, then blacking…

I also woke up during my wisdom teeth extraction. Likewise don't remember any pain, just being shaken as they tried to extract one of the teeth. Contrast that to my first eye surgery, for which I was completely awake, and the local anaesthesia wore off. That was hell. Excruciating pain while the doc had various instruments in my eye. I voluntarily stopped breathing as I clenched against the pain. Set off all sorts of…

I also woke up after a wisdom teeth extraction, while still intubated, choking, and remember the nurse pulling out the tube quite painfully (for me) while I was gagging.

The asshole anesthetist denied it happened.

Even if you don’t wake up during surgery, it feels like there’s an imprint of the trauma. I had a very long operation and by the time I came round I was in pieces emotionally, with no clear idea of what had happened but still a deep sense of dread. On some level it felt like my body knew what had just happened.

Are you sure that isn’t just the comedown from the anesthesia?

Could be! It’s an emotional moment and not a particularly nice place to wake up. But there’s definitely something at the back of your mind telling you something fairly awful happened. Of course your mind knows this anyway - you know you had surgery and have the scars - so it could all be an illusion.

As an anaesthesiologist (well, senior trainee), I hesitate to comment on this, but here goes nothing... I think it’s important to remember that the vast majority of anaesthesia delivered does not involve ‘general anaesthesia’ nor neuromuscular blocking drugs. Most patient’s experience of anaesthesia is sedation, where the aim is comfort, not absence of recall. There is a bit of a movement to reduce our reliance on ne…

Very interesting. I cannot recall having sedation outside of dental practices, but I have had several colonoscopies which involved counting down from 10, getting to about 8 and waking up hours later in recovery.

Interesting to see I'm sort of an outlier.

Many comments here mention waking up during wisdom tooth extraction. I've had two surgical wisdom tooth removals under local anesthesia. General anesthesia was never suggested to me, and frankly I can't see why you'd even want that when local anesthesia works just fine and is safer.

Is it common to have general anesthesia for wisdom tooth surgery somewhere in the world, maybe USA? I live in Finland.

One of my operations turned out problematic and slightly traumatic. No one wants stressful situations like that, of course. I'd still rather remember what happened and try to come to terms with it.

That happened to me too. I thought that was normal procedure?
